   6             [ 1043759 ] Selected character count
   7
   8     This patch implements a continuously updated count of
   9     selected characters in the status line.
  10     It only works for normal selections (not for
  11     rectangular selections) and it doesn't work when
  12     quadruple clicking to select the whole file.
  13
  14     It is a response to feature request 1040294, which
  15     asked for something similar.
  16
  17     Augmented to show rectangle dimensions when a rectangular selection is
  18     active.
